GUSTAV RAU, OF KANSAS CITY, MISSOUBL AIR-COOLED BLOCK FOR LINING XVALLS.

Application led April 29, 1926. Serial No 105.434.

This invention relatesl to aircooled blocks for building the inside walls ot' stills. ovens, boilers and thc like.

The primary object of thc invention is to 'u increase thc length of lite ot inside walls lor the purpose speciiicd and also to transmit air through thc blocks to driers tor drying coal.

A further object ot the invention is to provide a series ot air-coohd bloclv's embodied in a lining wall or belt having alincd openings therethrough in planes at right angles, to set up both horizontal and vertical air tlucs when the blocks arc assembled in the f wall structure.

A. still further object of the invention is to provide in connection with each of the aircooled blocks a removable 'and replaceable nose or surface section which serves to protect the remaining portion oll the block in rcar thereof. and when said removable nose or section becomes deteriorated by llanic or hoty gases from the tire in the still` oven. boiler or like device, it may be readily detached and another similar nose or section applied, the stationary part ot the block being so constructed that when the noso or section is removed. thc wall above will be supported and prcvonted l'rom falling.

H0 With the foregoing and other objects and advantages in view. thc invcntion consists in thc preferred construction and arrangement olI the bloclts which will be more l'ully hereiiri ttor described and claimed. .i ln the drawing:

` Fig. l is a longitudinal vertical section of a t'uruacc, showing a lining' wall or belt colnprisiug thc improved aircoolcd blocks.'

Fig. .2 is an enlarged transverse vertical section o? a lpart ol'l a furnace, wall and several otthe improved blocks applied thereto and illustrating the protective nose of one ofthe blocks removed.

llig. t) is a top plan view of one of the blocks .15 and the protective removable nose therefor.

Fig. t is a transverse vertical section on the line. itik1', Fig. 3, looking in the direction of the arrows and particularly showing,r the communication ot' the horizontal and vertical air n0 llucs of the block.

lhe improved block, as heretofore indicated, comprises two sections or members, namely, a body 5 and a replaceable noso or surtacc section 6. The body 5 is formed with :i5 a vertical web 7, a lower outward extension 8, and an upper, inward extension 9, both extensions being disposed in planes` at right angles to the web 7. The lower outward extension S is thicker than the inward extension 9 and said lower extension 8 is inserted in a groove 10, there being a plurality of the grooves 10 formed in the one end wall 11 of a furnace or other device 12 t0 which the improved lining or belt comprising the blocks i-s applied. These grooves 10 continue hori- 65 zontallv iu parallel relation through the inner side of the wall 11 and this wall is reduced in thickness to an extent'corresponding to thi,l combined thickness of the bodies 5 and protecting noses or surface sections (i of the ser eral blocks. The upper extension 9 of cach block is formed with a lower recess 133 at its i'rcc forward edge. said recess extendingr throughout the length of the said extension and the outer side ofthe web 7 continues from its point of intersection with the. lower side ot' the extension 9 fully to the bottom of tbc body 5. Applied over the inner side por( tions ot the block bodies 5 having the extensions 8 and 9 as above specified are the pro4 tec-ting noses ot' sections 6, thc latter having upper, inner flanges 1l of the same dimi-nn sions as the recesses or seats 13 and are rn ceivcd in the latter` the lower portions ot' thc noses of sections G having outwardly pro4 jccting extensions 15 which terminally abut against the lower outer portion of the bodiw` 5 adjacent to the extensions 8 of the said bodies. The noses orscctions 6 are substantially L shaped in t'o'an and contributc. in W combination with the bodies 5 and extensions 8 and 9, to form horizontal air fines lt'. ln

the outer free extremities of the extensions Svertical air tlues 17 are formed and in thc extension 15 of the nose or section (i similar w fines 18 are also constructed and alined with the upper vertical flues 17 and open into the horizontal air flues 1G. lVhen the blocks comprising,r the body members 5 and the protecting noses or sections G are assembled in a lining or belt formation with relation to the Walls of a furnace or other like device. all of the horizontal flues 16 are in alinenicnt and provide continuous air passages, and likewise, alLof the vertical flues 17 and '1S are in alinement and form a plurality ot' vertical air passages, and in connection with the end Wall 19 of the furnace or like device a manifold 2() is exteriorly applied over the outlets 21 of the horizontal air fines, the said manifold having a central pipe connection 22 for application theret'o of a tubular conducting,

pipe ronneeted to a fan or suction means, and whereby the hot air and gases may be drawn from the interior of the turnaee and. con- `veyed to a place of storage for coal, to dry the latter. It is also possible to use this Withdrawn hot air and gases for other purioses.

It `will, be seen that the lower reduced portion of each n'all to which the lower course of blocks comprisingr the bodies 5 and noses or sections t are applied l'orms a base support by theconstruction of a shoulder or ledge .23 as the result of the reduction in thickness of the walls` and the remaining roursil of blot-ks above are positively snpported in vertical arrangement as shown by Fig. l. The several bloek bodiesfhave their outward extensions 8 engagingr the grooves l() ot the wallsv` and these bodies are therefore held in trne applied position at all limes, or with the ivi-bs 7 extending;t vertically. `/Vhcn the deteriorated or burnt-out noses or sections are removed for replacenient by similar noses or sections to remove the inner side of the lining wall or belt, the superposed blocks will not inthe least be ailerted or displaced, owing` to the fact that the blocks successively above the lower Course "t bodies are held supported on the upper sides o1" the extensions 9 and thereby the entire wall is maintained in association with the walls ot the `furnace or other device, and fuitl'ierniore, when the noses or sections 6 are in association with the bodies 5, they are likewise held on the upper edges of the succeeding noses or sections. It will therefore he seen that the walls have at all times a stable application and will not become loose or disarranged.

As hereiolfore indicated, the principal feature ot the invention is the provision ot the ar-rooler blorks, or the formation ot the horizontal air tlues 16 and the vertical air fines l? at all times in communication with iluA ilur-s lo, and whereby the whole wall is rooled, with material advantages inthe struelure oi' the wadl of a jQurnaee or other device, and to this principal advantage is added the ron'x nieuw in replacing;` the inner side of the wall which becomes deteriorated or burntout` without ailecting the remaining: portion ol' the liningf or belt. with obvious economy in slruriurw; ol this character. A further advantage is tho provision for drawing healed air and ,grasos away from thil lining` wall or lit-ll comprising the improved aireoolcd blocks and their protective, rcnioval'ile components or noses or scetions 6.

The tivo members of each block, or the hody 5 and removable nose or section 6, are both 'fori'ned ot refractory material similar to that used for making high grade firebricl and ordinaril)v employed for l'i'irnace linings, and thti particolar ell'ect. of cooling the lining wall or beltis imposed upon the series of noses or sections 6 with the result that the latter parts will lastmaterially longer than would be the ease it there were no temperature lowering provision in the form ot' the continuous horizontal and vertical communicating air flues. The overhang oi' the brickwork is of such extent that it'does not bear upon the noses or sections 6, more than half of the brickwork restiner on the block bodies. Though it is proposed to standardize the proportions ol' the two components ot earh block for the purpose of economy in manufacture, it will be understood that at times it may he desirable to modify the dimensions and proportions thereof lo adapt the same to particular applications.

The removable noses or protective sections when withdrawn open the horizontal and verti ,al air passages and permit the latter to he freed ol' all aceumulation of products of combustion that may lodge therein, so that vthe air fiues or passages may be maintained in unobstructed condition.

lli/*hat is claimed as new is:

Air cooled blocks tor service as components of a liningr or belt for and combined with a furnace wall` each block comprising a vertical body member with an upper terminal inwardly projecting extension and a lower terminal outwardly pro'eeting extension, both extensions beine at planes at right angles to the vertical body7 member, and the upper extension havin; a lower angular inwardly openingr corner recess continuing fully over the width of the extension, and a removable and replaceable nose member having a vertical body and a lower outwardly projectingr extension which terminally abuts against the inner side ot the lower portion of the vertical bodv of the first named member with the hottornithereof flush with the bottom of the said outward extension of first. named member, the upper terminal ot the body of the nose member having a Bange fittingr in and flush with the recess ot the inner terminal of the upper inwardly projecting extension of said first named member, the upper inwardly projeeting extension ot the first named member and the lower outwardly projecting extension of the nose formingr a, central flue con` tinuing uniformly transversely through the complete block, and the upper inwardly projecting extension oi' the Erst named member and the outwardly projecting extension of the nose respectively having a pair of spaced vertical tlues opening in to said central flue. whereby when a number of the, completo blocks are assembled the said vertical tlues become continuons through all the blocks and communicate with thelhorizont-al tlues of the. blocks.

ln testimony whereof I have hereunto Vset my hand.
